Gemstones prices: How much do different gemstones cost?

For thousands of years, jewelry has been set with gemstones that turn a simple piece of jewelry made of precious metal into a sparkling jewel. The best known is the diamond, but there are also the 3 colored gemstones (sapphire, ruby, emerald) and a variety of other minerals that are called gemstones. Colored gemstones in particular are especially rare and have a high price in fine qualities, often much higher than white diamonds.  

The price of gemstones depends on many factors. Decisive is the size, the color, whether and to what extent inclusions are present and how good the cut is. For diamonds, these quality characteristics are called the 4Cs.

The question "What does a gemstone cost?" cannot be answered in general terms. However, we share our expert knowledge in this article to give you background knowledge and clarify which factors significantly influence the price.  

Within the gemstone and jewelry industry, prices are quoted in dollars or euros per carat (.ct) to create comparability. The weight of gemstones is measured in carats or carats, where 1 carat (.ct) equals 0.2 grams. Carat as a unit of weight should not be confused with carat as a measure of the purity of gold.

We focus on fine qualities of gemstones and give information depending on the type of gemstone, how the gemstone price or gemstone value is composed and what you have to be willing to pay for a 1 carat gemstone.

How much does a sapphire cost?

The sapphire is just like the ruby a variety of the mineral corundum and is after the diamond the second hardest mineral. Sapphires are particularly rare and valuable. Sapphires are found even rarer than white diamonds, depending on their color. The best known is the blue sapphire. What does a sapphire stone cost? This depends greatly on its color, clarity, size and cut. Provided a fine quality is given, a sapphire costs several thousand euros. For clarity, it is useful to quote prices per carat weight. What does a 1 carat blue sapphire cost? A 1 to 2 carat blue sapphire ("cornflower blue" or "royal blue") of top-quality retails for between €1,000 - €2,000 per carat.  

Sapphires come in all colors of the rainbow. There are from colorless, white sapphires also called leuco sapphire, also green, yellow, orange, pink or violet sapphires. Generally, in any color, lighter pastel shades are much cheaper than intense shades, due to their rarity. Pricewise, lighter shades usually cost half as much as an intensely saturated shade in the same color, depending on the color. A pastel, light blue sapphire costs 700€ - 1,200€ per carat.  

Pricewise, pink, and purple sapphires in intense color are equally valuable as blue sapphires in the top segment. This used to be different, but due to the rarer finds of this color and the rapidly increased and sustained demand, the market prices are comparable. Yellow, orange, and green sapphires are more common in nature and therefore cheaper. At one carat, these colors cost about the same as lighter blue sapphires. Means these colors cost just half of an intense blue and pink sapphire. White sapphires are the least expensive, costing no more than a third per carat compared to a blue sapphire.

How much does a Padparadscha sapphire cost?

Sapphires in this special color combination of "orange-pink" or "pink-orange" are the rarest sapphire color and the Padparadscha one of the rarest and highest quality gemstones in the world. This sapphire, whose color is reminiscent of the lotus flower and also from which it takes its name, are unusual. Their prices for natural stones can reach astronomical heights, especially if they are distinguished by color, purity. Padparadscha sapphires are much rarer in occurrence than blue sapphires, rubies or emeralds.  

The demand is so great and continues to grow that prices will surely continue to rise each year. What does a 1 carat Padparadscha sapphire cost? In fine quality and intense color saturation, this has a price per carat of 5,000 to10,000+€. For larger carat sizes, prices increase exponentially and often prospective buyers have to wait a very long time to even get a genuine Padparadscha Sapphire, regardless of price segment.  

You can find everything about the Padparadscha Sapphire on here on our website - a must for every gemstone lover to dive into the world of Padparadscha Sapphires and dream about its incredible beauty. Read more about Padparadscha sapphire – a complete guide

How much does a ruby cost?

The ruby is named from Latin for its deep red color. The ruby is a variety of the mineral corundum, as well as the blue sapphire with the same hardness. The trace element chromium is responsible for giving the ruby its red color. Thus, with more chromium content, a pink sapphire becomes a ruby. Because of its color, rubies come out of nature rarer than sapphires, this leads to a higher value of the ruby compared to blue sapphires.  

What does a ruby cost? For a fine quality ruby of 1 carat, you must pay at least 2,000€ to 5,000+€. For special specimens in the premium segment, 5,000€ to 10,000+€ is also realistic in this size. For larger carat sizes, prices increase exponentially. From this you can see that the question cannot be answered in a general way, besides the size, it is mainly the color or color saturation, the clarity and the quality of the cut that influence the value of a ruby.

Most valuable is the color variant "pigeon blood red". As with other gemstones, the clarity, color and cut of the ruby play a decisive role, in addition to the carat weight. Depending on where they are found, rubies have varying degrees of red coloration and fluorescence, which also significantly affect their value. The most sought-after rubies come from the Asian region, especially Myanmar (Burma) as well as from East Africa (Mozambique and Madagascar).  

Everything you need to know about the difference between pink sapphires and rubies can be found in our blog article, including many color examples: Ruby vs. Pink Sapphire - Classification, Color Difference, Value

How much does an emerald cost?

The term emerald also comes from the Greek and simply means "green stone". How valuable is it? With no other gemstone do prices vary so much, prices range from sometimes less than 50€ per carat to thousands and many thousands of euros per carat. Depending on the color intensity, its transparency, whether rather cloudy or completely transparent, due to its inclusion pattern and the cut quality its value is measured.  

Especially valuable are deep green stones, also called fir green, which are absolutely transparent than clear and luminous, due to their transparency and few inclusions to almost eye-clean emeralds. Price-wise, emeralds can be compared to rubies to some extent, even though they are usually priced a bit higher. What does an emerald cost? In the top segment, a natural 1 carat emerald is at least 4,000€ to 8,000+€ pay.  

Because the mineral beryl is very brittle, emerald is also considered particularly difficult to cut. A finely cut emerald is therefore also valued higher than one with a rough cut. Emeralds from Colombia are considered to be of particularly high quality, here a premium is paid on the market, depending on the deposit in Colombia for stones from "Muzo" even more than "Chivor". From Zambia comes currently the most volume, this is also very attractive together with emeralds from Brazil and a special deposit in Ethiopia.

How much does a diamond cost?

Diamond is considered the noblest of all gemstones, its hardness is 10, the hardest mineral in the world. It exists in many varieties of color, the price determined by the 4Cs: Color, Cut, Clarity and Carat.

The price range per carat is breathtaking, ranging from a few hundred euros for rather inferior diamonds to millions per carat for natural color diamonds in blue, pink and red. Colored diamonds are to be estimated in their rarity higher than pure white diamonds, so the price per carat can fluctuate even for yellow diamonds already quickly by many thousands of euros per carat.

The market for diamonds is transparent and liquid, which means there are reference prices depending on color and clarity, as well as cut and florescence for 1 carat diamonds. How much does a diamond cost? It costs as much as it is offered, since with the appropriate certificate (preferably from GIA) you can buy it anywhere, even on the phone, without ever having seen it. Therefore, do some research on the Internet and compare the qualities, since white diamonds can be graduated exactly based on their 4Cs to get a sense of price. As this example you can see that a price difference between a diamond in color G/H, clarity VS2/SI1, with very good cut (VG) and a diamond in color D, clarity IF with excellent cut, has a many times higher value per carat.

How much does an alexandrite cost?

A little known but fascinating gemstone is the alexandrite. Named after its discoverer in honor of Russian Tsar Alexander the Second. The first specimen was discovered very late, in the first half of the 19th century. It is a special form of chrysoberyl, the fourth hardest mineral of all, with a Mohs hardness of 8.5. It’s fascinating feature is a color change, depending on the type of light. Under daylight it appears rather greenish-bluish, in artificial light the color changes to reddish-violet. The strength of this effect, called pleochroism (multicoloredness) in technical language, is a decisive value-determining characteristic of alexandrite.  

Alexandrite is also among the rarest gemstones in the world, and minute differences in its quality can make a significant difference in value. In the top segment, there are alexandrites that have at least a 90% color change between daylight and artificial light. Also a beautiful, attractive green with little gray and brown parts and on the other side a reddish violet that appears strong over the whole surface of the stone.  

Alexandrite is rarely found in jewelry, but this does not make it any less desirable to collectors. How much is a 1 carat Alexandrite worth? Prices per carat vary widely, from a few hundred euros to prices of 30,000+€ per carat. Here, similar to sapphire, ruby, emerald, it is recommended to consult an expert and have the quality differences explained. After a brief introduction, anyone can see with the naked eye why the particularly rare <1% Alexandrites are so valuable. Alexandrite deposits from Russia have long been depleted. Russian alexandrites are often described as the finest on the market. In Brazil, the "Hematita" region had also produced fine qualities, but they are also almost exhausted. Currently, one finds good qualities on the market mostly from India, Sri Lanka, Madagascar or Tanzania.

What determines the price when buying a gemstone?

The quality and rarity of gemstones determines their value. There are 9 factors that influence their value. They are,

1) Color

2) Clarity

3) Cut

4) Carat

5) Country of origin

6) Shape

7) Certificate

8) Treatment

9) Supply chain

The first 4 factors are commonly called the 4C's of gemstones. Derived from diamonds, the 4Cs for gemstones give a good guide in determining quality. But this has since evloved to 5Cs, as the origin ("Country of Origin") has a value-determining influence for gemstones.

If you are interested in the 5Cs for sapphires, it is best to read all the background here: 4Cs + 1C = 5C's - Valuation of Sapphires

The 4Cs in Diamonds

Let's look at each of these 9 factors in detail.

1. Color - The color of a gemstone

The value of a gemstone depends strongly on its color. As a rule, color-intensive stones are more in demand, but there are of course a few exceptions.

Colored gemstones increase in price when they have rich or intense colors and the color is evenly distributed. Depending on the type, there are color varieties that are particularly sought after and are considered the ideal color.

Gemstones that are too light or too dark are usually less in demand than gemstones with medium hues. A rich cornflower blue or a vivid royal blue in sapphire is therefore considered more valuable than an inky blue-black or very pale blue hue.

In addition, natural colored stones are considered more valuable than those whose color has been subsequently enhanced by treatment.

2. Clarity - The Purity of a Gemstone

When determining the price of a gemstone, its clarity is considered first. A gemstone is considered pure if it is free of inclusions, that is, if there is no foreign material in the stone. This includes other minerals, gases, liquids, and also growth lines that interfere with the luster and play of light in the crystal.  

In general, the purer the stone, the better its luster. While it is true that the purer a gemstone is, the higher its value, certain inclusions that do not affect its luster and shimmer have no noticeable effect on its value. It should also be said that some gemstones, such as emerald, always have inclusions.

Colored gemstones are said to be eye clean when no prominent inclusions are seen when viewed from above, this is different to diamond. A diamond is considered absolutely pure if no inclusions are visible even under 10x magnification. The purity plays a decisive role especially with colorless gemstones. With colored gemstones such as the sapphire, ruby, emerald, inclusions and thus the purity may not reduce the overall impression of attractiveness, but one is more tolerant, because somewhere in the lower body of the gemstone inclusions are visible, also as an important sign of nature that it is not a synthetic stone.  

3. Cut - The cut and cut quality of a gemstone

A good cut brings out the best in the gemstone and enhances its beauty. It is through cutting that the sparkle of a stone comes out and even small blemishes in clarity can be made invisible through a skillful cut. However, with cutting, a large portion of the initial weight of the rough stone (from 50 to 80%) is lost.

Thus, the type and design of the cut can account for between 10 and 20% of a gemstone's value. Different types of gemstones are cut differently. For diamonds, the classic brilliant cut has become established; for emeralds, the emerald cut has become established; for other gemstones, such as opal, the cut is cabochon, i.e. not faceted.

To maximize the light reflected to the eye, gemstones must be cut in the correct proportions. Gem cutters often have to compromise when working on a specific piece. If the gemstone's color is fairly light, a deeper stone will yield a richer color when cut. A darker hue, on the other hand, can be made lighter with a shallower cut.  

It is important to know that the rough stone tells the cutter how best to cut the stone. Depending on inclusions and the color distribution in the stone, the cutter decides what nature tells him. A good cutter will optimize the clarity and brilliance and not just cut to get as much carat weight as possible, which unfortunately is very common. Also, you cannot standardize the depth or height of a colored gemstone as you can with white diamonds, for perfect brilliance most colored gemstones have a depth to length ratio of about 55 to 70%. Even though this is just a number, you can tell the difference in its brilliance and sparkle.

4. Carat - The size and weight of the gemstone

Of course, the size of the gemstone also plays a crucial role. The weight of gemstones is measured in carats / carats, where 1 carat (.ct) is equal to 0.2 grams.

High quality minerals are rarer the larger they are. So, the larger a stone, the higher its value per carat. In other words, the price grows exponentially with corresponding quality. A two-carat stone is therefore worth more than two qualitatively similar one-carat stones.

For certain gemstones, for example diamonds, the price per carat can increase exponentially with increasing size. According to this formula, a 1 carat stone might cost €2,000 and a 2-carat stone might cost €8,000. Although this formula is rarely so accurate, top-quality sapphires and rubies in larger sizes often have a much higher price per carat.

However, "calibrated" (the same in dimensions) stones can also command higher prices per carat in the trade because they are easier for goldsmiths to work with.

5. Origin - The place where a gemstone was found

For many colored gemstones, origin also plays a role in pricing. This is because certain regions or even individual mines are known for particularly beautiful stones. For example, the Mogok region of Burma is known as the place of origin for pure, intensely colored rubies, while the best emeralds are said to come from the Muzo mine in Colombia. For sapphires, it is the Myanmar (Burma) and Ceylon (Sri Lanka) localities with the finest qualities.

For classification, it can be said that a fine natural stone is a fine gemstone of the highest quality regardless of the country or area of its origin. However, in the market, depending on the type of gemstone, certain countries of origin, such as Burma, Sri Lanka, Colombia and Brazil, are highly priced in the market. This means that due to their rarity in the respective countries, along with the outstanding quality, a premium is paid in the market.

Whether this is justifiable is not easy to say, especially given the fact that so many fine gemstones come from Africa, but they are considered at a certain discount in value in the market. However, experience shows that prices are formed according to market mechanisms and particularly rare or already depleted deposits in the corresponding countries of origin are valued as rarer and thus more precious, which is also quite justified due to the aspect of rarity, even if you do not see this visually, you usually have a certificate or a gemstone origin report that indicates this additional value and thus hedges.

6. Shape - The shape of a gemstone

Certain shapes are often more expensive than others, partly in light of demand and partly in light of the material issues associated with cutting a specific shape. In general, round gemstones stand out on the market as being particularly high in price. In fact, round shapes are much rarer than oval shapes, as oval shapes are often cut to preserve as much raw material as possible. When cutting round gemstones, a larger portion of the rough is usually lost, and this can have a significant impact on the price of particularly expensive stones, such as sapphire, ruby, alexandrite, and others.

With special cut shapes, such as the emerald cut, square cushion cut, princess cut, you have a particularly high rough stone loss. This affects the price per carat. There is a cut for every taste. Just know that oval and elongated cushion shapes are usually a little cheaper than other cuts due to the lower loss of rough during cutting.

7. Certificate - A gemstone certificate increases its value

Exact information on how much gemstones are worth in total or per carat is difficult to give, because as described above, it depends on the individual nature of the stone.

Therefore, a gemstone certificate from an internationally recognized gemmological laboratory is mandatory for investment stones. Without a corresponding certificate, a gemstone will fetch a significantly lower price when sold than an equivalent certified stone.  

Independent laboratory certificates are becoming more and more popular in the market, this is also a proof of confidence in the stone from a neutral, third-party expert point of view. For all more valuable gemstones, a gemstone appraisal would always be recommended, as this specifies the gemstone criteria and also checks whether and what kind of treatment is present in the gemstone.  

In the course of certification, a gemstone is graduated, i.e. the individual characteristics of a stone are classified and recorded by independent experts. Some institutes also give an estimate of the price of the stone in the certificate. This is primarily used by insurance companies to insure a gemstone and is significantly higher than the market value for end customers, as a future loss of the stone is priced in, since special gemstones significantly increase in value over the years.

8. Treatment - How do treatments affect the value of the gemstone

Natural gemstones always have the highest value. Depending on the type of gemstone, there are traditional and market treatments that affect the visual appearance of the gemstone by optimizing the clarity and sometimes the color. Between pure nature and a common enhancement there are differences in value depending on the type of gemstone and its color. All further treatments, which are to be marked obligatory after the world-wide accepted CIBJO regulations, are to be enjoyed with caution, these diminish the value substantially since thereby nature - the natural appearance of the precious stone is clearly changed and with certain precious stones the market attaches only an optical and no lasting value to these precious stones, which means in the internal sense so much, it has no resale value.  

To name a few gemstone treatments, such as heat treatment on sapphires and rubies, crack filling on rubies and emeralds, irradiation, and diffusion on many other gemstones, greatly improves the appearance of many gemstones. These treatments are now routine for many commercial stones, although it must be said that chemical or even radioactive alterations by irradiation are a no go.  

A treated stone always costs less than a similar untreated stone. But most stones that are routinely treated - such as ruby and sapphire - are very rare to find in untreated form, and the untreated stones bring in a market price that most customers cannot afford. Based on history and market practice, 98-99% of all sapphires and rubies are heated (fired or heat treated). Any sapphire offered to you as "sapphire" is heated, only if it has the additional predicate "sapphire - no heat" (or "in natural color" or "no indications of heating") is it completely untreated in its most natural form of natural color and purity.  

Please read about the art of firing corundum (sapphire and ruby) to get an insight into how this treatment works and what improvements it traditionally produces: Heat Treatment of Sapphires

Sapphires before and after heat treatment

9. Supply Chain - What impact does the supply chain have on the price of the gemstone

The gemstone trade is a business, and all players in the supply chain - from the mine to the local seller have a profit margin. On their way from the gemstone mine to the end customer, gemstones pass through a great many hands. Clearly, the more market players involved in this process, the higher the price.  

Already in the countries of origin, the rough stones go through appropriate collector systems from the mine to the cutter already through 3 to 6 hands. After that come larger dealers for cut gemstones and exporters, so that one can say on average that a gemstone no matter what kind and country of origin has already gone through more than 10 market participants until it arrives on site in the goldsmith and the local jeweler.  

This is not bad per se, as this has always been the case and will not change. However, there are exceptions, gemstone producers and gemstone dealers who not only act as traders, but are also very close to the mines involved and can acquire the gemstones directly from the hand to be able to give a quality and price advantage to their goldsmith and jeweler partners. Unfortunately, this is often also just said, "I buy directly from the mines" or "I operate mines with partners", so it pays to look behind this and ask the right questions to get a really fine gemstone at an attractive market price.

Gemstone as an investment

Cut diamonds and colored gemstones have been a popular and recognized form of investment for centuries. Gemstones have survived all previous financial and economic crises unscathed and are particularly attractive due to their mobility. For example, a high-quality colored gemstone (sapphire, ruby, emerald) weighing 5 carats, equivalent to one gram, can have the same market value as 2 kilograms of gold. For this reason, gemstones have often been called "ideal currencies". Furthermore, gemstones are not subject to any property tax and are hardly affected by inflation, deflation or devaluation of money, which makes them so particularly attractive as an anonymous investment in tangible assets.

Of course, gemstones can and should only be a part of the investment mix, but not everyone can or wants to invest in real estate, antiques or works of art, and the international stock exchanges or financial markets can hardly be classified as a safe haven for a longer period of time. Even gold, the "No. 1 crisis currency", has shown clear downward tendencies after a record high and is always subject to great volatility. Fine gemstones are not subject to fluctuations, their prices always go upwards. Due to rarity and scarcity, the supply is very tight and the worldwide demand for gemstones is increasing and increasing, which leads to ever new price records.

A few criteria why gemstones are worthwhile as an investment. Gemstones are small, easy to transport and concentrate highest value in smallest space. They can be passed on simply and easily (e.g. to the next generation). Gemstones are traded internationally. Auctions drive prices. Gemstones have been used to store value for more than 5,000 years. Findings of gemstones (especially ruby & sapphire, also color diamonds) are declining worldwide. Former countries of origin in Asia as well as Russia provide high demand. Natural colored gemstones have shown a considerable increase in value for more than 40 years and are considered "non-volatile" (= stable in value). Gemstones are easy to store, do not cause any effort and do not require any service.

How much are gemstones worth?

The value of a natural gemstone can be a few hundred or a few thousand Euros. The value depends on the type of gemstone, its rarity, hardness, popularity and origin. Therefore, values can be very different.  

The price of a gemstone is based on several factors, especially its size, combined with its color, clarity and therefore its quality. For diamonds, these 4 quality criteria are called the 4Cs. Therefore, the question "what do gemstones cost?" cannot be answered in general terms.

Which stones are valuable?

The most valuable are diamonds, especially natural-colored diamonds and the 3 color gemstones sapphire: ruby emerald. Furthermore, special collector stones like the real Padparadscha sapphire, alexandrite, demantoids or special spinel colors.  

These gemstones are particularly valuable, because in top quality they are very rare to find on the market. Since very little or no more than current mining. On the other hand, worldwide an extremely high demand for these particularly rare gemstones. Due to their value development, these gemstones are ideally suited as an investment in addition to their beauty and individuality.

Which gemstones are the cheapest?

Gemstones or also called semi-precious stones e.g. quartz, topaz or garnet are the cheapest. Other cheaper gemstones are amethyst, peridot, citrine, ametria, tanzanite, aquamarine. These types of gemstones are the cheapest due to their higher volume in the market and lower hardness.  

A low price depends primarily on the type of gemstone and carat number (weight), but also due to its treatment and whether the natural origin or not. Of course, all artificially produced gemstones (syntheses) are much cheaper than the real jewels or have no real market value at resale, because it is popular can be reproduced frequently.  

Why are gemstones so expensive?

Because they are natural minerals and crystals of nature, which are found very rarely. The nature and rarity of a gemstone determined its value today and also in the future.  

The composition of the substances, the crystal system, the type of crystal lattice and the shape (habit) are also essential for the price of gemstones. In addition, there are factors such as: Carat, cut, hardness, luster or density. While with colorless gemstones the purity is decisive, with colored gemstones the saturation or intensity of the color plays a significant role.

What does 1 carat blue sapphire cost?

A 1 to 2 carat blue sapphire in intense color saturation of a top-quality cornflower blue or royal blue will retail for prices between 1,000€ - 2,000€ per carat. Quality stones of 2 to 3 carats sell for about double to triple the price per carat. Light blue or pastel blue sapphires are less expensive and cost about 700€ - 1,200€ per carat.

What does a sapphire stone cost?

The most valuable are intense blue and pink sapphires. Yellow, orange, green or white sapphires are less expensive. Pastel colored sapphires in all colors cost about half of an intense sapphire of the same color.

For gemstones, there is no universal grading system to grade a sapphire. However, for larger or smaller stones, prices can only be extrapolated to a certain degree, there is no linear or exponential formula to follow. Sapphires come in all colors of the rainbow.  

Is sapphire or ruby more expensive?

Rubies are more expensive than sapphires, it is the same mineral corundum, however the pure red variety ruby is found less often in nature, which significantly affects its value. 1 carat ruby in fine quality costs at least 2,000€ to 5,000+€.  

Very special rubies in the premium segment especially from Burma also quickly cost 5,000€ to 10,000+€ per carat. For larger carat sizes, prices increase exponentially.

Are gemstones a valuable investment?

Yes, gemstones are a great value investment due to their rarity and popularity as a substance value that is natural, physical and mobile. Ruby & Sapphire have a much better long-term performance than gold or the Dow Jones for example. Natural colored, untreated gemstones show no volatility and hardly correlate with world economic events. Over the past 25 years, market prices for natural colored, untreated gemstones have at least tripled. Rubies from Burma have even increased in value almost tenfold.

Which gemstones should you own?

These 3 colored gemstones are especially rare and have always been popular because of their beauty and rarity. For this reason, it is recommended to own sapphires, rubies and emeralds along with a white diamond.  

For collectors and people with large financial resources it is also advisable to own a natural-colored diamond, a padparadscha sapphire or an alexandrite, in order to have a special rarity of nature as one's own. As an investment, it is recommended neither to jump on trends nor to buy exotics, but to rely on common colored gemstones, which are always in fashion: First and foremost ruby, sapphire and emerald.  There has been a strong demand for these colored stones for centuries.

You should consider seeking independent legal, financial, tax or other advice to determine the extent to which the information on this website relates to your individual circumstances.

Where is the best place to buy gemstones?

Gemstones can be purchased in a physical store or online. Physical stores that sell gemstones are goldsmiths, jewelry stores or gem experts where cut diamonds, sapphires, rubies and emeralds are sold. It is important to have good advice, the professional expertise, and the international network of the seller to be able to offer fine qualities at a good market price.  

With gemstones, the smallest differences in color, clarity, cut can significantly affect the quality and price. For this reason, buying colored gemstones online is not recommended under any circumstances, as it is essential to have seen the gemstone in real and in daylight.  

Also, one should get to know the seller and verify his trustworthiness or expertise and confront him with the right questions about the origin, treatment and mining conditions of the gemstone on site. In the case of diamonds, buying online is quite possible as the 4Cs with an appropriate GIA certificate accurately describe the quality criteria and therefore one does not need to examine the gemstone live.
